take brute force approach and compile some test code to assembly (instead of machine code) and look for presence of references like _gxx_personality_v* (DWARF), _gxx_personality_seh* (SEH), _gxx_personality_sj* (SJLJ) see Obtaining current GCC exception model.build some real or test C++ code involving exception handling to force linkage with one of those DLLs and then see on which one of those DLLs does the built target depend (for example, can be seen with Dependency Walker on Windows) or.inspect directory and file structure of MinGW-w64 installation in hope to locate one of those DLLs (typically in bin) or.Hence, to find out what exception model does your current MinGW-w64 distribution exactly provide, you can either BONUSīy the way, the three corresponding dynamic-link libraries (DLLs) implementing each GCC exception model are If that doesn't work, then just build with i686-w64-mingw32-g++. On the other hand, plain old SJLJ distributions are indeed dual-target, and in order to build 32-bit target, just supply -m32 flag. mustafagonul: If you know the minimum version satisfying your requirements, and it's a couple of releases back, picking the latest & greatest instead is basically being intentionally annoying. they contain only the libraries with either 64- or 32-bit addressing, but not both. You can see it yourself by inspecting the directory structure of their distributions, i.e. Both DWARF and SEH variants (which come starting from GCC 4.8.0) are only single-target. So I'd prefer to not assume a fixed path to the 32-bit and 64-bit Java installations on the build machines.That depends on which variant of toolchain you're currently using. I forgot to mention that I implement the CMake build system to be used by many developers on their machines. I currently use CMake 3.14 but could update if it helps. To avoid that, I would like to have FindJava always find the 64-bit Java independent of the Visual Studio generator bitness. If you installed the binaries and images, then. Select INSTALL Build Build INSTALL will place the binaries in the directory designated with CMAKEINSTALLPREFIX. To find Java itself I apply the CMake finder module FindJava in a findpackage(Java) call. To create the build system I let CMake call some Java tools to generate some of the code to compile (applying Eclipse Modeling Framework). Build Solution - 10 minutes later should be all built. I apply CMake to generate a Visual Studio 2017 solution to build a 32-bit application on and for Windows 10. My problem is, that the 32-bit Java sometimes cannot allocate enough heap memory to execute the code generation tools. Open VS2010, open the UHD.sln 'Solution' file, and the many executables will show up. So, the Java version seems to depend on the bitness of the generator in use. For more information, see Install the C++ Linux workload in Visual Studio. Both C++ CMake tools for Windows and Linux Development with C++ are required for cross-platform CMake development. Note, when I call CMake to generate for Visual Studio 2017 圆4, FindJava returns with 64-bit Java. Installation C++ CMake tools for Windows is installed as part of the Desktop development with C++ and Linux Development with C++ workloads. I've observed that FindJava automatically selects the 32-bit version of Java in this case although a 64-bit Java is also available. I tried to compile cmake as a 32 bit application and did not manage to get it compile with Visual Studio 2019 while it works with Visual Studio 2017. To find Java itself I apply the CMake finder module FindJava in a find_package(Java) call. nitawa (Nabil Ghodbane) May 12, 2021, 6:46pm 1 dear experts, I installed both Visual Studio 2017 and Visual Studio 2019 on my Microsoft Windows 10 workstation. I apply CMake to generate a Visual Studio 2017 solution to build a 32-bit application on and for Windows 10.
